parallel ng_pptp_rcvdata():
- Add a per-node mutex.
- Acquire mutex during all ng_pptp_rcvdata() method.
- Make callouts protected by mutex. Now callouts count as
netgraph writers, but there are plans to allow reader callouts
for nodes, that have internal locking.
- Acquire mutex in ng_pptp_reset(), which can be triggered
by a message or node shutdown.

1. Walk the absolute list in reverse to prefer duplicated levels that have
a lower absolute setting, i.e. 800 Mhz/50% is better than 1600 Mhz/25% even
though both have the same actual frequency. This also removes the need to
check for already-modified levels since by definition, those will be added
later in the sorted list.
2. Compare the absolute settings for derived levels and don't use the new
level if it's higher. For example, a level of 800 Mhz/75% is preferable to
1600 Mhz/25% even though the latter has a lower total frequency.
This work is based on a patch from the submitter but reworked by myself.

Copies the data portion of mbuf (chain) n starting from offset off
for length len to mbuf (chain) m. Depending on prep the copied
data will be appended or prepended. The function ensures that the
mbuf (chain) m will be fully writeable by making real (not refcnt)
copies of mbuf clusters. For the prepending the function returns
a pointer to the new start of mbuf chain m and leaves as much
leading space as possible in the new first mbuf.

m_sanity()'s main purpose is for KASSERT()'s and debugging of non-

in the chain will be cleaned too.
This function is used before an mbuf, that arrived as packet with
m->flags & M_PKTHDR, is appended to an mbuf chain using m->m_next
(not m->m_nextpkt).

interrupts for multiple wi devices, having a global check to make sure
at most one of them was in wi_cmd no longer makes sense.

- Document the fact that a subsequent listen(2) calls on the listening
socket change the backlog argument.
- Note that current listen queue lengths can be queried using netstat(1).

- On resume all registers have to be initialized again like after
power-on so reset sc_inited in gem_suspend() in order get all of
the registers set next time gem_init_regs() is called.
- On at least some ERI and GEM revisions GEM_MAC_RX_OVERFLOW happen
often due to a silicon bug and re-initializing is all we can do
about these errors so make handling them non-verbose.
- Remove a superfluous memset(3) call in gem_meminit(), all elements
are initialized to 0 anyway.
